Abstract: Most high level interpretation task rely on image alignment process. In this work, a method for automated image alignment through image segmentation is proposed. The image data need to be analyzed, preferably by automatic processing techniques because of the huge amount of data. This new approach mainly consists in combining several segmentations of the pair of images to be registered. It can be applied to a pair of satellite images with simulated translation, and to real remote sensing examples comprising different viewing angles, different acquisition dates and different sensors. This process allows the alignment of pairs of images (multitemporal and multisensor) with differences in rotation and translation, with small differences in the spectral content, leading to the subpixel accuracy.
